Segfaults [ON HOLD]

[pkofod]

Edit: On hold... So apparently Pkg.update is really giving me a hard time today. JuMP is suddenly version 0.11.3, and the segfaults happened because it took me back to master from develop. Now I can't run anything... I'll close if I resolve it.

So, I updated my CUTEst.jl and now I am getting segfaults

using CUTEst, Optim
for i = 1:100
    nlp=CUTEstModel("CLIFF")
    optimize(x->obj(nlp,x), nlp.meta.x0)
    cutest_finalize(nlp)
end

Can you replicate this?

Hey @pkofod, we're in the middle of some big changes, and Pkg.update probably won't get them. I think that

Pkg.clone("https://github.com/JuliaSmoothOptimizers/NLPModels.jl")
Pkg.checkout("NLPModels", "develop")
Pkg.clone("https://github.com/JuliaSmoothOptimizers/CUTEst.jl")
Pkg.checkout("CUTEst", "develop")
Pkg.build("CUTEst")

can give you a working version, after you fix the dependence problems.

By the way, I've had the same problems with MathProgBase and JuMP before. I think that Pkg.free("MathProgBase") or something in this line fixed it for me.

All seems to be working now. I ended up simple deleting all package files and started from scratch, adding one package at a time. So I should clone from JuliaSmoothOptimizers from now on? edit oh, you renamed it . Then I think there is no more to add to this discussion.

[abelsiqueira]

Yes, we just changed the name. Will release soon(ish) too.

Good to see this getting attention, I really think it's going to improve our understanding of the performance of Optim.
